Air-gasification at low temperatures (733-773 K) of chars from Spanish coals catalysed by V,O, has been studied and the results have been compared with those obtained previously using copper as catalyst. Under the reaction conditions, both catalysts showed high activity due to their ability to under
Cellulosic chars prepared at HTTs ranging up to 500ยฐC contain aromatic structures as evidenced by the production of benzene polycarboxylic acid derivatives on permanganate oxidation. Analysis of these products indicates the concentration of the aromatic units and the degree of substitution of benzen
